Application filed April 7,

'This invention relatesto a printing device employing .a changeable formand an `inking ribbonoverlyingthe form, and more particularly such a device where lthe form is on a rotary drum and'coacts with aroller platen.`

The object of the invention is to provide simple means for enabling the ready instaldiately ,extends across such form.A In such Tcas e,fI 'provide a channel: adjacent thebody form which leads tothe endiof Vthe drum andwhich furnishes a'passagewayor `the reception oli-the removable portionlof .the

l@dans tor` holding itin piace; To enable the removable formtobe readabout the drum, I provide a bridge in the formota thin metal strip extending across the Channel just withinthe region covered "by the'ribbon. The removable portion of Vthe form'is Iinsertedfinto place beneaththis' I* bridge with its printing lportion'beyond the same. '.'Ifhebridge is located beyond the endv o f the platen so that itv ldoesfnot-interfere with the proper printingfaction.'

As shown' in the drawings, the printing machine proper comprises a rotarydruml 10 mounted on a shaft 11 journalle'd invend `fralnepla'tes land above'a roller platen 14' 'mounted on ashaft 15. Gearing .16.and

yl'i'fandy anOldham coupling 18 connect the drum and platen. Anysuitablemeans, as for vexample a crank '19, is provided forrotating-the fdrum'fand' platen;

I have shown meansmounted onthedrum 29 of the drum and-heldinlpl'aceby.-suitable `means las hook-like -inembersQly engaging the shaft 111 lAninking ribb'on"25isshown as mountedvon spools 27 carried'betwee'n-the -end members otthefdrum, such "-ribbo'nf-fextending intermediately about the stype vtorm.

It will kbe seen-that inthe construction vdescribed,whenthe drum fis rotated, as by meansof the crank, paper fed between =the ydrum-'and platen may be `printed 'by 'the typel characters through 'the ribbon. The

-pape'rgmay be fed-'byhand or in-soineautomatic manner it. desired.

The `removable portionf'otfthe Aform as illustrated in the drawing comprises an address plate A. vThis plate is V:showfnas provided with overhang-ing projections @Pfand soV depressed edgeportions a2 "under'curled on i themselves `for strength. The projections invention `is hereinafterfmore :fully eX- ,pliied and its essential novel; characteris` I may carryfeinbossedprinting strips (L.

The drum segment Qljis provided with `a longitudinal channel 30- leading ,fromn-one `end ot the drum Jfor the-reception :of the removable portion of the form. lI-"have .shown a, supporting portionj32 in this Chanvflanges, theserecesses ino - To enable the plate to passV readily under the ribbon, l employ a bridge 40extending across the channel. This bridge is prefer- `ably aflat piece of spring metal intermediately curved concentrically of the drum and having depressed end portions Which are suitably secured to the segment, as by means of a screw 41. The vbridge is v located just within the region of the inlriiig ribbon so that it supports the extreme edge portion of the ribbon Without interfering With its outer side of the bridge, and the segment may be recessed beneath it as at 45, whereby. the plate may be readily grasped bythe lingers and withdrawn. It may be held in A pliace by friction or otherwise during the operation of the machine. A portion of the end member 12 may be removed as at 46 Fig. l to enable access to the channel 30. By stopping the drum with the channel in register with such re- -cess in the frame plate, the installed plate `may be readily removed and a substitute inserted beneath vthe ribbon as illustrated by the broken linesA in Fig. l.

An inspection .of Figs. 5 and 6 illustrates the .e difliculty in inserting the plate particularly .beneath a' ribbon stretched about a drum, due to the fact that the taut ribbon .tends to form. a chord across Vthcchannel while the printing surface of the inserted plate is arcuate. By providing a correspondingly arcuate bridge suiiiciently high to .clear the inserted member, as illustrated parj ticularly in Fig.. 3, I overcome the difficulty and enable'the readyinsertion of the plate. Fig. 6 shows at 25 theposition of the ribbon across the channel Way. beyond the bridge, While the brokenlines show how vthe end of the address plate would abut the ribbon if the bridge were not employed.

The bridge may be located in the vertical plane which is just beyond the end of the platen, as the* ribbon raised by the bridge will readily be pressed against the adjacent type in operation. Y

Having thus described my invention, I.
